Sensor layer can be optically transparent or opaque.If the sensor layer of particular is arranged on display In device, then sensor layer can be optically transparent, so as to not influence the clarity of display.In another example, sense Device layer is arranged around the periphery of display, and below the frame around display.In this embodiment, sense Device layer needs not be optically transparent.

Position stylus

Next, touching on surface 108 is inputted to electronic equipment 102 with reference to using the sensor layer of electronic equipment 102 This operation that pen 104 is positioned.Electronic equipment 102 can by it is a variety of it is suitable in a manner of 104 tip of stylus is positioned And estimate its cartesian coordinate.

In typical embodiments, as the collaboration results between stylus 104 and electronic equipment 102, stylus 104 is determined Position.In general, stylus 104 can produce the electric field with smaller effective diameter.When stylus is placed on input surface, the electricity Intersect with input surface field.Electronic equipment 102 detect the electric field, and based on the position (and/or region) for detecting electric field come Estimate the position of stylus.The electric field that can be generated by stylus 104 is more fully described with reference to figure 5A to Fig. 5 M in detail below.

More particularly, as described above, electronic equipment 102 can include sensor layer, which can be configured as Detect the electric field produced by stylus 104.In one embodiment, sensor layer includes multiple capacitive sensing nodes.Capacitance sense Survey node can be located at display on or within and/or input surface 108 on or within any suitable layer on or Between.

In some instances, capacitive sensing node can be formed by optical clear conductor at least in part, such as but unlimited In：Metal oxide, such as tin indium oxide and antimony tin；By nano-silver thread, carbon nanotubes, Pt nanowires, nanowires of gold etc. The pattern of nanowires of formation；The deposition of thin metal；Etc..Capacitive sensing node can be configured as with self-capacitance pattern, mutual capacitance Pattern or the operation of other capacitives, it is capacitively coupled to stylus 104 and detects resulting signal and electric field.

In these embodiments, stylus 104 can form the made of substantially spherical electric field produced from its tip.The electric field Influence the mutual capacitance of each capacitive sensing node near tip.Electronic equipment 102 is by monitoring each capacitive sensing node These capacitance variations simultaneously are estimated the position of such change (if there is) occurs, to be carried out to the stylus 104 on input surface 108 Positioning.

As used herein, term " tip signal " typically refers to be applied to the electric signal of tip 104b by stylus 104.Such as this Used in text, term " delamination tip-field " typically refers to the electric field as caused by the tip 104b of stylus 104 in response to tip signal.As above Described, delamination tip-field can take any suitable shape, but in many embodiments, delamination tip-field it is substantially spherical in shape and It can be modeled as point source monopolar electrical field.Intersect with delamination tip-field on input surface 108 (or plane parallel with input surface 108) Region is generally referred to herein as " delamination tip-field intersection region ".

The circumference of delamination tip-field intersection region can be defined as such border, and from the border backward, electronic equipment 102 receives The power density (for example, intensity) of delamination tip-field be less than selected threshold value.In one example, the circumference quilt of delamination tip-field intersection region It is limited to half power points (for example, 3dB points) place of delamination tip-field.In other words, in this example, delamination tip-field intersection region is defined For that part intersected in input surface 108 with delamination tip-field, half of its intensity at least above the power for producing the electric field.Under The exemplary knot that can be configurable to generate and/or launch delamination tip-field is described in detail referring in particular to Fig. 3 A and Fig. 5 A to Fig. 5 N for text Structure.

Because delamination tip-field is produced from the tip of stylus 104, delamination tip-field intersection region is substantially based only upon stylus 104 position and shift；In typical embodiments, delamination tip-field intersection region may be not based on the Angle Position of stylus 104 and with Virtual manner shifts.Therefore, in order to determine the position of stylus 104, electronic equipment determines the geometric center of stylus intersection region.So And as it would be appreciated, the sensor layer of electronic equipment 102 can be disposed in one below the outmost surface on input surface 108 At set a distance.In these examples, delamination tip-field intersection region can depend on stylus 104 Angle Position (for example, perspective shrink/ Parallax effect).

In other embodiments, the position of stylus 104 can be determined by electronic equipment 102, stylus 104 or its combination. For example, electronic equipment 102 can determine delamination tip-field periphery shape, the maximum position of delamination tip-field, the minimum position etc. of delamination tip-field. In other words, it will be understood that although some technologies are described herein, electronic equipment 102 or stylus 104 can use Other suitable technologies determine the position of stylus.

In many cases, same sensor layer can be used for one or more finger of detection user 106, examine at the same time Survey delamination tip-field.In these cases, electronic equipment 102 can receive touch input and stylus input.Specifically, capacitance sensing Node can be operated under touch input pattern to detect finger touch, and is operated under instrument input pattern to detect stylus Input.Both patterns can be switched over such speed：Under the speed, capacitive sensing node can be at the same time or almost same When detect finger and touch (multiple point touching or single-touch) and stylus and input.

The Angle Position of stylus

With reference next to Figure 1B to Fig. 1 D, behaviour of the stylus 104 relative to the Angle Position on input surface 108 is estimated involved in figure Make.In these embodiments, stylus 104 can produce the second electric field that is discrete with delamination tip-field and biasing.Second electric field and point Field co-axially align is held, and thus the two allow the grasping of stylus 104 all along the longitudinal axis for axis symmetry of stylus 104 Situation is unknown.

In order to ensure delamination tip-field and the second electric field are axisymmetric, many embodiments utilize the conducting ring with minor diameter Or pipe produces the second electric field.In some embodiments, the diameter of conducting ring is approximately equal to the electric conductor of generation delamination tip-field Width (for example, in one millimeter).It is responsible for the signal wire of tip signal transmission to tip 104b passing through conducting ring.With this side Formula, the field produced by conducting ring can be axisymmetric；The electric field is from the responsible letter by tip signal transmission to tip 104b The influence there are situation of number line.

As used herein, term " ring signal " typically refers to the telecommunications for being used to produce the second electric field applied by stylus 104 Number.In many embodiments, since the diameter of annular electric conductor is small, the second electric field is also made of substantially spherical electric field. In other words, although the source of the electric field is ring shaped conductor rather than point source, with conductor and tip, (and therefore, electronics is set Standby 102 input surface 108) (under the distance, ring electric field shows as being derived from point separated distance for electronic equipment 102 Source monopole) to compare, the radius of conductor is sufficiently small.

In some embodiments, annular electric conductor is pipe or cylinder.In these embodiments, caused electric field It can be in capsule shape (for example, the cylinder covered with hemispherical end).In these embodiments, ring shaped conductor have along The longitudinal axis of the longitudinal axis alignment of stylus 104.By this way, one of the capsule shape electric field produced from tubular electric conductor Domed ends, are oriented as the tip 104b towards stylus 104.

As delamination tip-field, as used herein, term " ring field " typically refers to be produced in response to ring signal by stylus 104 Electric field.The region that input surface 108 (or plane parallel with input surface 108) is intersected with ring field is usually claimed herein For " Huan Chang intersection regions ".

In other embodiments, the Angle Position of stylus 104 can be by electronic equipment 102, stylus 104 or its combination Lai really It is fixed.For example, electronic equipment 102 can determine ring field periphery shape, the maximum position of ring field, the minimum position etc. of ring field.Change Sentence is talked about, it will be understood that although some technologies are described herein, electronic equipment 102 or stylus 104 can use it His suitable technology determines the Angle Position of stylus.

Therefore, it is however generally that, stylus (such as stylus 104) as described herein produces two different electric fields, its field source phase Mutually biasing a certain distance.The electric field is aligned with each other along the longitudinal axis of stylus so that the electric field is axisymmetric.The One electric field is come near stylus tip end, is referred to as delamination tip-field.Second electric field comes from biases part away from delamination tip-field small distance, is referred to as Ring field.Delamination tip-field and ring field are substantially spherical (or hemispheric) on the direction at stylus tip.When in use, delamination tip-field With the ring field input surface on delamination tip-field intersection region and intersection region with electronic equipment (for example, electronic equipment 102) respectively (for example, input surface 108) is intersecting.Under many circumstances, intersection region can be substantially circular.

As delamination tip-field intersection region, the circumference of Huan Chang intersection regions can be defined as such border, from the border Backward, the power density (for example, intensity) for the ring signal that electronic equipment 102 receives is less than selected threshold value.In one example, ring The circumference of field intersection region is limited at half power points (for example, 3dB points) place of ring field.In other words, in this example, ring field Intersection region is defined as that part intersected in input surface 108 with ring field, its intensity is at least above producing the electric field The half of power.Ring can be configurable to generate and/or launch by being described in detail in detail below with reference to Fig. 3 A and Fig. 5 A to Fig. 5 N The example arrangement of field.

Tip signal each can exchange electric component with ring signal with least one, and the exchange electric component is via capacitive coupling Or other suitable detection technologies are received by the sensor layer of electronic equipment.In many embodiments, the frequency of tip signal Frequency or modulating mode (for example, channeling) different from ring signal.In other cases, tip signal and ring signal can be with It is time-multiplexed.

However, it is different from delamination tip-field, since the field source (for example, annular electric conductor) of ring field is separated with tip 104b, so Huan Chang intersection regions can the Angle Position based on stylus 104 and shift.Therefore, stylus is tilted in one direction or another 104 cause the area of Huan Chang intersection regions and/or position to change, and delamination tip-field intersection region remains substantially stationary.

In these embodiments, the relative position of delamination tip-field intersection region and Huan Chang intersection regions can be used, to estimate Count polar angle and the azimuth of stylus 104.More particularly, the geometric center of delamination tip-field intersection region and Huan Chang intersection regions is apart More remote, stylus is relative to the polar angle on input surface 108 with regard to smaller 104 (for example, stylus 104 is more parallel to input surfaces 108).Class As, can be using the angle of the vector limited between delamination tip-field intersection region and the geometric center of Huan Chang intersection regions, to estimate Count azimuth of the stylus 104 relative to input surface 108.

In another non-limiting phrase statement, in many embodiments, electronic equipment 102 uses delamination tip-field and ring The known spherical diameter of field, the diameter of Huan Chang intersection regions, and/or the distance between tip and ring, to estimate (the limit of polar angle 118 It is scheduled between the vector of plane and the longitudinal axis 120 (such as zenith) of stylus 104 on input surface 108) and azimuth 122 (being limited between the reference vector (such as axis) in the plane on polar angle 118 and input surface 108).

For the ease of understanding the relativeness between polar angle 118 and azimuth 122, there is provided Fig. 1 C and Fig. 1 D, show in figure The additional views of the electronic equipment 102 and stylus 104 shown in Figure 1A are gone out, and have for the sake of clarity eliminated user's 106 Hand.Fig. 1 C show the top view of the electronic equipment 102 of Figure 1A, specifically show stylus 104 relative to input surface 108 Plane azimuth 122.Similarly, Fig. 1 D show the bottom side view of 102 electronic equipment, and stylus has been shown in particular 104 input the polar angle 118 of the plane on surface relative to electronic equipment.

Many embodiments are described herein with reference to the sensor layer of electronic equipment 102, which can be configured as Tip signal and ring signal are detected by monitoring mutual capacitance.It is understood, however, that electronic equipment 102 can be with any Mode specific to specific implementation is suitably configured, to detect ring field and delamination tip-field.For example, electronic equipment can include sensing Device layer, it is configured as the self-capacitance change for monitoring one or more capacitance sensor nodes.In other examples, electronic equipment It can be configured as operating under self-capacitance pattern and mutual capacitance mode.In other embodiments, other sensing skills can be used Art determines the position of delamination tip-field and ring field and relative position.

As described above, sensor layer can be used for one or more finger of detection user 106, while detect ring field. In these cases, electronic equipment 102 can receive touch input and stylus input.

Figure 1B is returned to, estimation involved in figure is applied to the power F on input surface 108 by stylus 104_aOperation.As at this Other embodiments of text description are the same, and the power applied by stylus 104 can in many ways be estimated, measured, be estimated, or Otherwise obtain.

In some instances, which is estimated by electronic equipment 102.In other examples, should by the estimation of stylus 104 Power, after this, stylus 104 use any suitable coding or uncoded form to be passed estimated power as vector or scalar Defeated (for example, via wireless communication interface) electron equipment 102.In other embodiments, obtained by electronic equipment 102 Power estimated result and the power estimated result obtained by stylus 104 can be combined, averagely or otherwise be used to estimate together Count the size of the power applied by stylus 104.

Initially, the power F applied by stylus 104 is estimated with reference to electronic equipment 102_aEmbodiment.In these embodiments In, electronic equipment 102 can include the one or more for being configured as estimating and/or estimating the power for being applied to input surface 108 Component.When input surface 108 is being contacted at the tip for estimating stylus 104, electronic equipment 102 is estimated to be applied by stylus tip Power F_a.In these embodiments, can be as the power perpendicular to input surface 108 as the power estimated by electronic equipment 102 Vector obtains.In these cases, electronic equipment 102 can use polar angle 118 and azimuth 122 that force vector is decomposed (example Such as, using cosine law) into the vector component parallel to the longitudinal axis 120 and parallel to input surface 108 component (for example, according to Above-mentioned technology calculates).Electronic equipment 102 can be by the component parallel to input surface 108 and the angle position parallel to stylus 104 The size of one or both of the component put or direction are interpreted as user's input.

Next, estimate to be applied to the power F on input surface 108 with reference to stylus 104_aEmbodiment.In these examples, Stylus 104 estimates the reaction force F that the stylus is subjected to itself_rReaction force F_rIt is equal in size and input is applied to by stylus 104 The power F on surface 108_a, and it is opposite with the latter on symbol.

In another embodiment, power sensing structure can be integrated in the penholder 104a of stylus 104.Power sensing structure can be with Including multiple independent strain-responsive elements or force-responsive element, these elements are arranged at each position along penholder 104a. When detecting one or more power (for example, one or more finger from user 106), stylus 104 can be by these power point Solution into and/or be combined into single vector parallel to longitudinal axis 120.More specifically, in these embodiments, stylus 104 are set to tip 104b at the fulcrum of second level lever.By this way, if power sensing structure is on 104 penholder 104a of stylus Each position at the sum of zero of each power that detects, then stylus 104 it is estimated that stylus 104 tip 104b not with Input surface 108 contacts.If on the contrary, detected by each position of the power sensing structure in 104 main body of stylus each The summation of power is not zero, then stylus 104 may infer that remaining power must be applied to input surface 108 by tip 104b.It Afterwards, the power F that stylus 104 will can be applied by tip 104b_aIt is transferred to electronic equipment 102.

Coordination between stylus and electronic equipment

As described above, the user input systems 200 described in Fig. 2A can be configured as positioning stylus 204, and Estimate the Angle Position of stylus 204.Cooperating between the coordination engine 206 of stylus 204 and the coordination engine 220 of electronic equipment 202 Promote these operations.Described above is the general interoperability of the two coordination engines.However, for the ease of understanding in more detail The coordination engine 206 of stylus 204, there is provided Fig. 2 D.

Fig. 2 D show the exemplary system diagram of coordination engine 206, which can be combined with stylus, such as reference The stylus 204 of Fig. 2A to Fig. 2 C descriptions.As pointed by other embodiments as described herein, coordination engine 206 can quilt For generating electric field (for example, delamination tip-field and/or ring field), electric field permission electronic equipment 202 positions and estimates the angle of stylus 204 Position.

In addition, coordination engine 206 can be configured as the power that estimation is applied to input surface 218 by stylus 204.More specifically To say, coordination engine 206 can be configurable to generate delamination tip-field (not shown), generation and/or transmitting ring field (not shown), and Detection is applied to the power 218 on input surface by the tip of stylus 204.Although this is provided as an example, at some In embodiment, it can be sensed by the individual aspect of stylus 204 to perform field generation and power.

In many embodiments, coordination engine 206 receives tip signal from processing unit 208 (for example, see Fig. 2 B), And by tip signal transmission to tip field generator 232.Similarly, coordination engine 206 receives ring signal from processing unit 208, And ring signal is transferred to ring field generator 238.In a further embodiment, it is attached in response to receiving additional field signal The field generator added can produce additional electric field.

The other information related with user, stylus and/or electronic equipment or data can be utilized modulate tip signal and/or Ring signal.For example, tip signal and/or ring signal, which can include stylus identity information, subscriber identity information, stylus, sets letter Breath, force information or any other information suitable for particular.

Coordination engine 206 includes tip field generator 232.Tip field generator 232 can suitably be led by any amount of Electric material is formed.Tip field generator 232 may be coupled to inelastic signals conduit 234.Inelastic signals conduit 234 can include firm Property part, the rigid element be configured as between the component of inelastic signals conduit 234 is connected to provide machinery coupling.In addition, Inelastic signals conduit 234 can include the core components passed through by one or more shielded signal lines.Below with reference to Fig. 3 A to Fig. 6 G Exemplary tip field generator and inelastic signals conduit is described in detail.

Inelastic signals conduit 234 tip field generator 232 is electrically coupled to processor in coordination engine 206, circuit or Electric trace.By this way, coordination engine 206 via inelastic signals conduit 234 by tip signal transmission to tip field generator 232.In addition, tip field generator 232 is mechanically coupled to power sensing structure 236 by inelastic signals conduit 234, this has in detail below Thin description.

Tip field generator 232 can be selected to the shape of inelastic signals conduit 234 electromagnetic screen is provided Cover.More particularly, the length of inelastic signals conduit 234 can be made choice, so as to by tip field generator 232 and stylus 204 other electronic units separate specific minimum range.Therefore, the tip signal produced by tip field generator 232 is subject to 204 subsystems of stylus (such as, processing unit 208, power subsystem 210, wave point 212, and/or power connector 214, or any other system or subsystem of stylus 204) influence of operation is small as much as possible.

Tip field generator 232 and inelastic signals conduit 234 can be completely enclosed within the shell of stylus 204.At these In embodiment, tip field generator 232 is molded in case material in which can be embedded into formula so that tip field generator 232 Positioned as close to the outer surface of stylus 204.Tip field generator 232 and stylus are described below with reference to Fig. 6 A to Fig. 6 G The relative position of 204 shell.

In many embodiments, tip field generator 232 is formed as the circle being orientated with the end towards 204 tip of stylus Shape shape, it can be configured as engagement input surface 218.Due to this shape, tip field generator 232 can be at least in delamination tip-field The electric field (for example, delamination tip-field) being roughly spherical is produced on the direction that the circular shape of generator 232 is orientated along it.In other words Say, tip field generator 232 substantially can be used as electric field point source.Electric field can be close to radial uniformity.By tip field generator 232 delamination tip-fields produced can be axisymmetric.

In some cases, the center of tip field generator 232 can be considered as the origin of ball point field.Input surface 218 can be mathematically modeled as the plane that intersects with ball point field.Therefore, delamination tip-field intersection region shows plane and ball The shape of shape cross-shaped portion, i.e., it is circular, and independent of direction.However, although delamination tip-field, input surface and delamination tip-field intersection region can To be mathematically modeled as sphere, plane and circle respectively, it is to be understood that, the reality produced in certain embodiments is several What shape may only be similar to spherical, plane and/or circle.

When delamination tip-field is substantially spherical, delamination tip-field intersection region (or part) is the plane in input surface 218 Interior border circular areas, the center in the region can the almost or exactly equal to positions of tip field generator 232.The half of border circular areas Footpath may be influenced by the amplitude for the tip signal for being applied to tip field generator 232.

Next, the ring field generator 238 referring to coordination engine 206.As tip field generator 232, ring field occurs Device 238 can be at least partially connected to inelastic signals conduit 234.In many examples, ring field generator 238 is formed in rigidity In or around signal catheter 234.For example, ring field generator 238 can be formed on the outer surface of inelastic signals conduit 234.

Ring field generator 238 and 232 coaxial alignment of tip field generator so that delamination tip-field and ring field also coaxial alignment. In many cases, ring field generator 238 and tip field generator 232 are separated by a distance.Retouched below with reference to Fig. 5 A to Fig. 5 N The relative position of tip field generator 232 and ring field generator 238 is stated.

As tip field generator 232, ring field generator 238 is electrically coupled to coordination engine by inelastic signals conduit 234 Processor, circuit or electric trace in 206.By this way, coordination engine 206 believes annular via inelastic signals conduit 234 Number it is transferred to ring field generator 238.Ring field generator 238 is also mechanically coupled to power sensing structure 236 by inelastic signals conduit 234.

In some embodiments, ring field generator 238 may be implemented as around the outer surface of inelastic signals conduit 234 The conducting ring of setting.Ring field generator 238 can be separated with tip field generator 232, and can usually be had than delamination tip-field The surface area of 232 bigger of generator, although not all embodiment is required for so.Ring field generator 238 can be formed For ring-type, so as to allow inelastic signals conduit 234 by do not influence ring field it is axisymmetric in a manner of by tip signal transmission to delamination tip-field Generator 232.In these embodiments, the ring field produced by ring field generator 238 can be axisymmetric.

In these embodiments, inelastic signals conduit 234 includes at least one path, which defines by wherein Electrical connection section.In some cases, which can form before ring field generator is formed.Inelastic signals conduit 234 The trace being arranged in inelastic signals conduit 234 is electrically coupled to ring field generator 238 by electrical connection section.Under many circumstances, mark Line is shielded.As shielding as a result, the ring signal of shielding can be transferred to ring field generator 238 by inelastic signals conduit 234.

Ring field generator 238 can be formed by any amount of suitable conductive material.In some instances, ring field generator 238 are formed by metal.In other cases, ring field generator 238 is formed by the conductive material deposited, such as metal oxide or Metal dust.Exemplary loop field generator is described in detail below with reference to Fig. 5 A to Fig. 5 N.

Since ring field generator 238 is separated with the tip of stylus 204, so the Angle Position of stylus 204 (being rotated from tip) Influence input the distance between surface 218 and ring field generator 238.For example, if stylus 204 is defeated with very sharp angle contact Enter surface 218 (for example, stylus is lay substantially flat on input surface), then ring field generator 238 can be smaller away from input surface Distance.On the contrary, if stylus 204, perpendicular to input surface 218 (such as 90 degree of angles), ring field generator 238 is positioned to Away from input 218 relatively large distance of surface.In this way, when the polar angle of stylus 204 changes, ring field generator 238 traverses input surface 218 The arc of top；When stylus 204 is perpendicular to input surface 218, there is the zenith of the arc.

As it would be appreciated, generality description above is related to the coordination engine 206 of stylus 204, the coordination engine and life Into can be related with ring field by the delamination tip-field that the coordination engine 220 of electronic equipment 202 detects.As described above, the association of electronic equipment 202 Regulate and guide and hold up 220 and can be configured as detection delamination tip-field and Huan Chang, and correspondingly detect delamination tip-field intersection region and the Huan Chang zones of intersection Domain.Hereafter, electronic equipment 202 compares the relative position of delamination tip-field intersection region and Huan Chang intersection regions, to estimate stylus Position and the Angle Position of stylus.By this way, coordination engine 206 and coordination engine 220 coordinate cooperation, so that with high accuracy Determine that stylus 204 inputs position and the Angle Position of the plane on surface 218 relative to electronic equipment 202.

In many examples, the cooperation of coordination engine 206,220 allows user input systems 200 with more defeated than traditional stylus Enter the more energy efficient mode of system to operate, which includes single electromagnetic digitizer, the electromagnetism number Word converter is used for for stylus power supply (for example, induction power supply, resonant inductance coupling etc.) and receives from it and interpret input two A purpose.In addition, the disposal ability needed for coordination engine 220 can be less than the traditional stylus input for including electromagnetic digitizer Disposal ability needed for system.Therefore, user input systems embodiment as described herein can be to be inputted than traditional stylus Less delay of uniting is operated.

Coordination engine 206 can also be estimated to be applied to the size of the power on input surface 218 by the tip of stylus 204.Below Description detection stylus 204 is applied to an exemplary method of the size of the power on input surface 218；It will be appreciated, however, that this is only An example, and other embodiments can by another have specify implementation detail and it is suitable in a manner of detect stylus 204 power applied.

As mentioned above for described in other embodiments, the tip of stylus 204 can be approximately along the longitudinal axis (for example, such as Figure 1A The shown longitudinal axis 120) moved relative to the main body of stylus 204.Specifically, tip field generator 232, ring field generator 238 and/or inelastic signals conduit 234 can be configured as：The power on input surface 218, phase are applied in response to the tip of stylus 204 Position is shifted, translates, recalls or otherwise changes at least in part vertically to the shell of stylus 204.

For example, it is to be understood that although describe these and other embodiments herein with reference to strain sensitive electrode, but It is that may include that any power is quick and/or strain sensor for particular.Similarly, cantilever column can take any conjunction Suitable shape.

In general, Fig. 5 A to Fig. 5 N are real with reference to the difference of the inelastic signals conduit of the coordination engine of stylus as described herein Apply scheme.User manipulates stylus to change the relative position of delamination tip-field and ring field.Electronic equipment calculates the relative position of field, and In response, position and estimate the Angle Position of stylus.

For example, Fig. 5 A show the side view of a part for the coordination engine 500 of stylus.With on Fig. 3 A described in implementation Scheme is the same, and coordination engine 500 includes being configured as receiving the tubular shielding part 502 of core insert 504 wherein.Tubular shielding Part 502 has a hypocrateriform part 506, and control panel 508 can be positioned on wherein (or thereon).Tubular shielding part 502 has hollow bulb Divide 510, wherein being placed with core insert 504.

Core insert 504 can be configured as the electric signal received from control panel 508 being transmitted to 512 He of tip field generator Ring field generator 514.In some embodiments, ground loop 513 may be provided at tip field generator 512 and ring field generator Between 514.Ground loop 513 can help prevent the capacitive coupling between tip field generator 512 and ring field generator 514.

Core insert 504 can be the signal path of shielding；Can be by one or more signal roads in core insert 504 Footpath is shielded with other signal paths, to prevent capacitive coupling therebetween.

When assembled and operation, tip field generator 512 can generate and/or launch delamination tip-field 516, and ring field is sent out Raw device 514 can generate and/or launch ring field 518.Delamination tip-field 516 and ring field 518 can be different power generation, such as Fig. 5 B Shown, its middle ring field 518 is with than the generation of the power of 516 higher of delamination tip-field.In other cases, delamination tip-field 516 and ring field 518 with Substantially the same power generation, it is all as shown in Figure 5 C.

Tip field generator 512 can be configured as generating the electric field of substantially almost spherical when from specific range estimating (for example, ring field).In other words, tip field generator 512 substantially can be used as electric field point source.

Although ring field generator 514 is annular, ring field 518 is substantially spherical in many embodiments.More specifically Say that as will be understood by the skilled person in the art, the electric field generated by ring-type element can be modeled according to below equation in ground：

Aforesaid equation describes the geometric center for the ring-type element for being r with the radius for being applied with charge Q when basis apart Distance for a estimated when, the size of electric field E.It is recognised that coulomb constant k provides zoom factor and single-bit correction, with essence Really estimate electric field E.

When the distance a of the geometric center away from annular field generator is much larger than radius r, electric field E is approximately equal to：

Therefore, it is more than ring field for the distance between input surface of its middle ring field generator 514 and electronic equipment to occur The embodiment of the radius of device 514, ring field 518 can seem substantially spherical for input surface, although ring field generator 514 be not at least geometrically point source.

In other words, it is selected to be less than for many embodiments, the radius of ring field generator 514 from ring field generator 514 arrive the distance on input surface.By this way, ring field 518 is to be seemed by an electric charge generation for inputting surface Substantially spherical electric field.By this way, both delamination tip-field 516 and ring field 518 are at least on the direction at the tip of stylus It is substantially spherical.

Although however, herein with reference to the automatic adjustment by electronic equipment inner sensor interblock interference to, by stylus The coaxillay aligned spherical field generated describes many embodiments, but such configuration may and not all embodiment institute It is required that.In some instances, non-spherical shape can be presented in the ring field generated by ring field generator.For example, ring field generator can It is configurable to generate the shape generally in cone.In this example, Huan Chang intersection regions can be conic section (for example, Hyperbola, ellipse, circle etc.).In other examples, ring field generator can be configurable to generate more than one electric field.For example, ring Field generator can be configurable to generate four electric fields generally in cone, each equably be spaced apart from each other.Conical electricity Field can be associated alternately or from different ring signals in polarity so that adjacent conical electric field will not mutually be done Disturb.In this example, Huan Chang intersection regions can be a series of conic sections (for example, hyperbola, ellipse, circle etc.).Therefore can To understand, any suitable electrical field shape or a series of electric field shapes can be generated by the ring field generator of particular Shape.

Tip field generator 512 is formed as being inverted the shape of light bulb.Point of the rounded ends in bulb-shaped portion towards stylus Hold end orientation.Rounded ends can be substantially spherical, or in other embodiments can be generally in hemispherical.Bulb-shaped The butt in portion is oriented as extending to the inside of stylus.The rounded ends in bulb-shaped portion can be configured to act as electric field point source.Change Sentence is talked about, and the rounded ends in bulb-shaped portion are formed as following shape, which can generate generally in ball from the rounded ends The electric field of shape.In many cases, the butt in the bulb-shaped portion of tip field generator 512 is with away from bulb-shaped round nose Portion and diameter reduce.The reduction of diameter can be constant, stepped, or can follow mathematical function such as exponential damping Function.

Ring field generator 514 can be formed by any amount of suitable conductive material.In some instances, ring field generator 514 are formed by metal.In other cases, ring field generator 514 is formed by the conductive material deposited, such as metal oxide or Metal dust.

Ring field generator 514 can be formed in any suitable manner.In many situations, many examples (and as shown in the figure) In, ring field generator 514 is arranged on the outer surface of core insert 504.Ring field generator 514 can be used any quantity suitable Manufacturing technology is arranged on the outer surface of core insert 504, and the manufacturing technology includes but not limited to：Physical vapour deposition (PVD), arteries and veins Impulse light deposition, certainly adhesion conducting film, metallic float technology, metal plating technique etc..In some embodiments, ring field is sent out Raw device 514 is formed using laser direct structuring technique and is formed directly on the outer surface of core insert 504.

Ring field generator 514 can be couple to ring signal line in a manner of any electricity is suitable.In one example, inserted through core Ring signal line is connected to ring field generator 514 by the path 520 for entering part 504, which may terminate at stent electrode 522 In.In many cases, path 520 takes the shape of recess (for example, inverted conical).Path 520 connects stent electrode 522 To ring field generator 514.The suitable manufacturing technology of any quantity can be used to be arranged on core for electrical connection section 520a through path 520 On the outer surface of insert 504 or the internal side wall of path 520, the manufacturing technology includes but not limited to：Physical vapour deposition (PVD), Pulsed laser deposition, certainly laser direct forming, adhesion conducting film, metallic float technology, metal plating technique etc..In some feelings Under condition, path 520 can be filled up completely by metal material, although this may not be required.

As pointed by the embodiment described in figure 3 a, tip signal wire terminates at the end of core insert 504 Engagement pad 524 at portion.In these embodiments, engagement pad 524 can be couple to delamination tip-field hair in a manner of any electricity is suitable Raw device 512.

As pointed by other embodiments as described herein (and as shown in the figure), tip field generator 512 and length coaxial alignment of the ring field generator 514 along core insert 504 so that delamination tip-field 516 and ring field 518 are axial right It is accurate and be axisymmetric.As it would be appreciated, the delamination tip-field 516 of many embodiments and the spherical nature of ring field 518 are easy to Stylus on input surface is positioned and in addition estimates the operation of its Angle Position.

Core insert 504 can configure in many ways.For example, with specific reference to Fig. 5 E, it illustrates work as to intercept by line D-D When core insert 504 cross section, core insert 504 may include the multilayer circuit board 526 being arranged in electrolyte blocks 528.For Simplified explanation, eliminates the layer of multilayer circuit board 526 from Fig. 5 D to Fig. 5 E, but it is understood that, multilayer circuit board 526 can have any appropriate number of layer being orientated in any suitable manner.In one example, multilayer circuit board 526 has There are eight layers.

Electrolyte blocks 528 are usually formed by plastics or another suitable electrically insulating material.In order to increase rigidity, electrolyte blocks 528 can be doped with fibrous material such as glass.

In many examples, path 520 can be defined during the molding of electrolyte blocks 528 and multilayer circuit board 526.Example Such as, multilayer circuit board 526 can be maintained in mould by supporting item, and when being removed after molding, which limits logical Road 520.

Multilayer circuit board 526 may include to be arranged at any specific and suitable position along the length of multilayer circuit board 526 Any amount of suitable components.For example, multilayer circuit board 526 may include (and/or can be couple to) one or more electricity Sub-circuit component (not shown), such as, but not limited to：Processor, resistor, capacitor, inductor, transistor, signal wire, connect Ground wire, grounding points etc..In many embodiments, the component for being couple to multilayer circuit board 526 is posted with reducing and/or eliminating The mode of raw capacitance is arranged and is distributed.Specifically, the layout of the component of multilayer circuit board 526 can be selected to reduce or eliminate Crosstalk (for example, parasitic mutual capacitance) between tip signal wire 530 and ring signal line 532.This is probably what is be especially desired to, to prevent Only electronic equipment detects ring signal due to delamination tip-field, and electronic equipment is similarly prevented and detects tip due to ring field Signal.

For example, as shown in the figure, tip signal wire 530 separated by a plurality of ground signal line 534 with ring signal line 532 and every From.In this embodiment, it is (every to separate two tip signal wires for physically and electrically for six independent ground signal lines It is a to be identified as tip signal wire 530) and two ring signal lines (being each identified as ring signal line 532).By this way, it is more Bar ground signal line 534 provides the electric isolution between ring signal line and tip signal wire.

In many cases, the external surface area through the various signal wires of multilayer circuit board 526 can also be selected, to reduce The possibility that parasitic capacitance is formed.Specifically, ground signal line, tip signal wire and ring signal line can be relatively thin； The external surface area of any signal wire is bigger, and the change that can form parasitic capacitance is bigger.In many embodiments, such as illustrate Embodiment, each signal can by more than one signal wire transmit (for example, two signal lines transmit ring signal, two letter Number line transmission tip signal, six signal lines ground connection) so that signal quilt at tip field generator 512 and ring field generator 514 Receive, without significant resistance loss caused by thin due to single signal line.

As it would be appreciated, although the embodiment illustrated depicts two ring signal lines of separation and two tip signal wires Six ground wires, but required by such quantity and not all embodiment.In some cases, it may include more Signal wire or less signal wire.In some cases, the signal wire for transmitting identical signal can be by one or more paths (not Show) link together at the difference of the length along multilayer circuit board 526.

As described above, engagement pad 524 is arranged on the end of core insert 504.In many cases, engagement pad 524 is welded It is connected to the end of core insert 504.In other cases, engagement pad 524 by suitable technique (such as, but not limited to：Physics Vapour deposition, pulsed laser deposition, certainly laser direct forming, adhesion conducting film, metallic float technology, metal plating technique etc. Deng) be formed on the end of core insert 504.

The multilayer circuit board 526 of core insert 504 may terminate at fill part (unmarked), and plurality of path is by multilayer Multiple layers of circuit board 526 are electrically coupled to same electronic circuit or signal wire.In many embodiments, in path and signal wire Each be electrically coupled to tip signal wire 530.Cut for example, Fig. 5 F are shown by the line E-E of Fig. 5 D along fill part The cross section of the core insert 504 taken.For clarity, engagement pad 524 not shown in Fig. 5 F.

During manufacture, multilayer circuit board 526 can be cut by fill part, so that one or more paths 536 and one or more signal wire 538a, 538b are exposed.One or more signal wire 538a, 538b can parallel to or it is vertical In the length of multilayer circuit board 526.In other examples, signal wire can be orientated in another way, such as be taken along a certain angle To.By this way, exposed path and signal wire (it is couple to tip signal wire 530) show big total in cutting Conductive surface area.Any suitable method can be used to be couple to engagement pad 524 (or one as the engagement pad for the large area Point).Increased surface area provides more mechanical systems and sound electrically between tip signal wire 530 and engagement pad 524 Coupling.

In some embodiments, engagement pad 524 can be unwanted；The exposed area of filling region can be used for tip Signal is sent to tip field generator 512.In other cases, engagement pad 524 can be provided in the exposure of filling region The deposit of conductive material in product.

The length of the filling region of core insert 504 can be different because of embodiment, and may depend in manufacture core insertion Achievable manufacturing tolerance during part 504.For example, if specific specific implementation is manufactured with low tolerances, filling region can be Long (for example, the certain distance that extends internally in the length of multilayer circuit board 526).In other cases, if specific tool Body is implemented to manufacture with high tolerance, then filling region can be short.It is understood that similarly, the quantity and density of path Can be because of embodiment and different.Similarly, the quantity of signal wire and density (although orientation) also can be because of embodiment and different.

Next, with reference to figure 5G to Fig. 5 I, generation (different size of) delamination tip-field 516 and ring field 518 illustrated therein is The side view of stylus, delamination tip-field and the ring field are each intersected with the input surface 540 of electronic equipment.Specifically, these figures Show when stylus is tilting on inputting surface, (in addition and by the top view of removal supplementing) delamination tip-field intersection region The relative position of 542 and Huan Chang intersection regions 544.

Fig. 5 G are shown when stylus is orientated perpendicular to input surface 540, delamination tip-field intersection region 542 and the Huan Chang zones of intersection The relative position in domain 544.Specifically, 544 coaxial alignment of delamination tip-field intersection region 542 and Huan Chang intersection regions.

Fig. 5 H show that delamination tip-field is handed over when stylus is orientated (for example, being tilted to the left) with acute angle polar angle to input surface 540 Pitch the relative position of region 542 and Huan Chang intersection regions 544.Specifically, delamination tip-field intersection region 542 is maintained at and Fig. 5 G institutes The substantially the same position shown；However, 544 shifted left of Huan Chang intersection regions.

Fig. 5 I show that delamination tip-field is handed over when stylus is orientated (for example, being tilted to the right) with acute angle polar angle to input surface 540 Pitch the relative position of region 542 and Huan Chang intersection regions 544.Specifically, delamination tip-field intersection region 542 is maintained at and Fig. 5 G institutes The substantially the same position shown, however, 544 right shift of Huan Chang intersection regions.

The operation of the positioning stylus of position based on delamination tip-field intersection region and Huan Chang intersection regions can complete it is as follows, still It should be understood that embodiment given below is only many that can be used for during positioning stylus by electronic equipment One in methods and techniques.Similarly, it is to be understood that equation given below and technology are only example, and Related to those presented below or incoherent many sides can be used during all stylus as described herein are positioned Method and equation.

Fig. 5 J show the stylus of Fig. 5 G, specifically illustrate stylus relative to the plane on the input surface of electronic equipment The azimuth φ and polar angle θ of Angle Position.

In these embodiments, it is however generally that, the electronic equipment scanning multiple sensors associated with input surface 540 To obtain tip signal.Estimate one group of adjacent sensor detect tip signal there are when, electronic equipment can be estimated Described group of geometric center.As described above, the adjacent sensor of the group is usually in the shape of circle.Hereafter, electronic equipment record should The geometric center organized is relative to the coordinate of the origin on input surface 540, the replacement coordinate as the position of tip field generator (proxy), and more typically as stylus tip portion contact input surface 540 point replace coordinate.For example, flute card There is the circular geometric center (x of radius r in your coordinate system_c,y_c) can be by the way that at least two estimations on the circumference of the circle will be fallen Point (x_m1,y_m1) and (x_m2,y_m2) below equation group is substituted into estimate：

Equation group presented above can solve；Only two known variables are geometric center (x_c,y_c) coordinate.With This mode, electronic equipment can determine stylus on input surface by calculating the geometric center 546 of delamination tip-field intersection region 542 Position on 540.

Based on the position of delamination tip-field intersection region 542 and Huan Chang intersection regions 544 come determine the Angle Position of stylus (for example, Azimuth φ and polar angle θ) operation can complete it is as follows, it should be understood that, embodiment given below be only can One in many methods and techniques during Angle Position for determining stylus by electronic equipment.

For example, if the cartesian coordinate of the geometric center 546 of delamination tip-field intersection region 542 is (x_t,y_t), and ring field The cartesian coordinate of the geometric center 548 of intersection region 544 is (x_r,y_r), and tip field generator 512 and ring field generator 514 separated distances are d, then can be simulated or a kind of method of the polar angle θ of approximate evaluation stylus by below equation：

In this case, when the distance between the center of delamination tip-field intersection region 542 and Huan Chang intersection regions 544 is approximate It is separated equal to tip field generator and ring field generator apart from when (for example, stylus input surface on it is as flat as possible), it is inverse Cos operation produces the polar angle θ close to 0 radian.

Alternatively, when the distance between center of delamination tip-field intersection region 542 and Huan Chang intersection regions 544 is approximately equal to zero When (for example, stylus is perpendicular to input surface), inverse cosine computing produces closeRadian or 90 degree of polar angle θ.

Similarly, the azimuth φ of stylus can be calculated.As it would be appreciated, it is (such as flat to refer to any suitable vector Row is in the reference vector of the horizontal axis (for example, x-axis) of cartesian coordinate systemCarry out estimation orientation angle φ.It is appreciated that It is that any suitable reference vector parallel with the plane for inputting surface 540 may be selected.For example, in some cases, it can be used The reference vector parallel with the vertical axis (for example, y-axis) of cartesian coordinate systemIn another example, can be used into Reference vector at any angle.

It can will pass through the center (x of delamination tip-field intersection region 542_t,y_t) and Huan Chang intersection regions 544 center (x_r,y_r) and The stylus vector of definitionThe cosine formula of dot product is input to, to estimate the angle between stylus vector sum axis vector.Example Such as, which can be carried out by below equation：

In this case, when delamination tip-field intersection region 542 and Huan Chang intersection regions 544 geometric center 546,548 it Between horizontal distance (for example, regardless of polar angle θ, stylus is arranged essentially parallel to the vertical axis on input surface when being approximately equal to zero Line), inverse cosine computing produces closeRadian or 90 degree of azimuth φ.

Alternatively, when the vertical range between delamination tip-field intersection region 542 and the center of Huan Chang intersection regions 544 is approximate etc. When zero (for example, regardless of polar angle θ, stylus is arranged essentially parallel to the horizontal axis on input surface), inverse cosine computing produces Close to 0 radian or 0 degree of azimuth φ.

In a further embodiment, delamination tip-field and Huan Chang can be generated in another way.For example, Fig. 5 K to Fig. 5 M are shown The side view of generation (formed objects) delamination tip-field 516 and the stylus of ring field 518, delamination tip-field and the ring field is each and electronics The input surface 540 of equipment is intersecting.Specifically, the figures illustrate when stylus input surface on tilting when, (in addition and Supplemented by the top view of removal) relative position of delamination tip-field intersection region 542 and Huan Chang intersection regions 544.

Fig. 5 K are shown when stylus is orientated perpendicular to input surface 540, delamination tip-field intersection region 542 and the Huan Chang zones of intersection The relative position in domain 544.Specifically, 544 coaxial alignment of delamination tip-field intersection region 542 and Huan Chang intersection regions.In the example In, Huan Chang intersection regions 544 are probably undetectable.

Fig. 5 L show that delamination tip-field is handed over when stylus is orientated (for example, being tilted to the left) with acute angle polar angle to input surface 540 Pitch the relative position of region 542 and Huan Chang intersection regions 544.Specifically, delamination tip-field intersection region 542 is maintained at and Fig. 5 K institutes The substantially the same position shown, however, 544 shifted left of Huan Chang intersection regions.

Fig. 5 M show that delamination tip-field is handed over when stylus is orientated (for example, being tilted to the right) with acute angle polar angle to input surface 540 Pitch the relative position of region 542 and Huan Chang intersection regions 544.Specifically, delamination tip-field intersection region 542 is maintained at and Fig. 5 K institutes The substantially the same position shown, however, 544 right shift of Huan Chang intersection regions.In other examples, when the polar angle of stylus During reduction, the big I increase of Huan Chang intersection regions 544, such as shown in Fig. 5 N.
